Abstract: An end section of a plastic fluid line with a push-in fitting is injection molded on coaxially for sealed push-in connection to a mating element of complementary shape with the aid of a securing element which transmits axial forces. The assembly formed of an end section and push-in fitting has a first circumferential groove on the end section, in the region of which the push-in fitting is molded on with form-fitting penetration of the plastic of the push-in fitting into the first circumferential groove. The end section, in the joining direction of the push-in fitting, protrudes axially beyond the latter and has a second circumferential groove for receiving a sealing ring. A third circumferential groove for receiving the securing element is molded into the push-in fitting on the outer circumference thereof.
